Capitalism isn't money in search of goods and services - it's a type of economic system.
I've copied this from Investopedia:
Economics is a social science studying how people allocate scarce resources for production, distribution, and consumption, both individually and collectively.
Capitalism supports private ownership of the means of production and enforcing private property rights to provide incentives for investment in and productive use of productive capital.
The capitalist economy is unconcerned about equitable arrangements. The argument is that inequality is the driving force that encourages innovation, which then pushes economic development. The primary concern of the socialist model is the redistribution of wealth and resources from the rich to the poor, out of fairness, and to ensure equality in opportunity and equality of outcome. Equality is valued above high achievement, and the collective good is viewed above the opportunity for individuals to advance.
